To all whom it may concern:

Be it known that I, WILLIAM Hoaacn DEAD, a sub'ect of the King of Great Bntam and Irelan and residing at Elswick Wor Newcastle-upon-T e, in the county 0- Northumberland, ngland, have invented certain new and useiul improvemettits 1n and relating to means or increasing e energ of stored compresed air or other capable. of supporting combustion, of which the following is a specification.

This invention relates to heating apparatussuchasisusedincomprasedalr plant. In such plant it is known to increase the energy of compressed air by burning therein a li uid fuel and also to introduce water into t e hot combustion products in order to reduce the temperature of the gases passing to the engine, and thus to enable an increased quantity of motive fluid to be made available without exceeding a suitable temperature. Should, however, the water supply for an reason fail, serious damage will he caused by the high temperature of the products of combustion.

The object of the present invention is to provide an apparatus of the above character, in which the disastrous effects resulting from the failure or variation of the water sup ly are avoided, and other ad vantages obtained. t

The invention consists for this pa .in making the feed of fuel into the comm chamber de dent upon the supply of water or 0 er vaporizable liquid into the products of combustion.

The invention also consists in connecting the fuel reservoir with the means so plying water or other vaporizable 1i unfmto the products of combustion in sac a manlnger tliiat a definitlelpjar'th of ti: waterlor other qua passing n sal supp y means is caused to enter said fuel reservoir and thus to displace the fuel into the combustion chamber the prefiure of the said water being utilized for spraying the fuel when desired.

By this invention, it'will be seen, that not only are the disastrous efi'ects resulting from failure of the water or other liquid su ply but also that the rate of of fuel into the combustion chamber can be made directly proportional to the rate of ,the

supp y of water into the products of combustion. Thus 'in the ratio of fuel to water areavoided and the bat profrom the water conduit to the fuel reservoir ismadeinthecockitselflFigis'apart sectional view (onthe lineal-A of 1 or a: of the water distributing device shown in use figures.

In invention into effect according to one method as suitable for a pedoandinwhich'uaterisfedfroniarm:- ervoir as shown in 1,, the air iS f0d 8.- reducing valve, 6, a tion chambe e, a conduit, d, which causes d p. of t v in as jarbe ucedorincrW f r ie'mb see i or .other suitable p within e, con uit or t I it hich of 9 m fleas n22 vleyingtgme i t etopo atank, gcontalmng" l npm liquid which to as water. oft-he con tank g a p1 conveys the. water to a' suitable 'et 0r u i, placed for example, in the side of com.-

bustion chamber, 0. A strainer j, is prefi." erably provided in the pi II, to against blockage of the pa e. It' be seen that the water is fed into the combint-ion chamber 0 by the difierence of pressure occasioned by the restriction e in the air supply pipe, d, to the combustion chamber 0. Intermediatebetw'een the water tank, g, and the jet or other spraying derice, is placed a connection, 1:, leadiufitbgthe bot tom of a-fuel oir, m. of the 16 water therefore along pipe, k, to the combustion chamber, 0. is diverted along this connection to enter the fuel chamber, m, and thus fuel is forced from the top of the container and passes 15 through a ipe, 11, into the combustion;

31 means of a suitable jetor chamber, 0,- distributing evice, -u:. The spraying of "the fuel may of course be assisted by means on an air stream if desired. The end of the ower end of the fuel reservoir m, may be appropriately shaped or baflled so that the entering water oes not tend to become mixed with the fuel, and further appropriate bafles, 0, may be placed in the mgchurned up from the rolling of the torpedo; The fuel reservoir, m; 15 also -provided with suitable means such as the cook p, for draining olf the water and also for refilling it with fuel, such as the plug, y, the fuel indyaporizable liquid such that they do nottend to mix with one another.

As shown in Fig. 1, the pipe, f, conveythe air to the water tank and the pipe, h,

convey amber and -the the water to the bottom 0 voir and theipe, a, conveying the fuel from the top 0 the reservoir to the combustion chamber may allbearranged ipe, is, leading the fuel resercontrolled by a single safety cock, q, or the th like. Insuch-acaseImay arrange, ifdesired-that the connection between the water gpfllydto the'oombustion chamber and to resei'voir'ma take place throuzh a a r, in'the 000 g, as shown in Fig.

3, l'thenplace a between the water tank, g,-nnd thococlr, g, and with this the strainer, j, may be retained or with as desired. The feed of water into the combustion chamber may be in any ap ropriate manner, for QI- u'nple, by the me ods described for feeding'in fuel in British Patent: No. 3495 of 1905 and U. S Patent No. 914,975 or as ascribed for bothwater and fuel' in up 4 plication Serial No. 412,921, The combustion chamber, c; may be provided with a deflector plate, a, .and with a primer I, no-

' cording -bo the before mentioned Patent Norm, (the ipe, z, supplying air to the rimerisnot of earness) and the restriction,- e, placed in the pipe, d, may be dispensed with and the necesary drop of prasure obtained be suitably set forth in th a t ficification or by reducing pipe, (I. The'water be- 1 A H .into the combustion any appropriate jet or i, may if desired,- be led a va coil-as described in my specification Serial No. 412,921. The fitm of. jet or spraying device which 1 ipe, k, which conveys the water into the;

reservoir, an, to prevent the water and fuel from be- 5 the water therefrom to the com-' tube;

own in full for the sake the deflector plate, 8, as

prefer shown in Fig. 4 and it will be seen that the water is introduced in the form of one or more jets the direction of which is more or less tangential to the surface of the combustion chamber, a. the water is restricted shown at, u and the desired energy of discharge to gave a good distribution around the'walls of the. combustion chamber is obtained by suitably proportioning the areas of the discharge holes, 1', and of this restriction, u. "hcn this form of distributing device is used asshown, with a combustion chamber inning a deflecting plate, 8, according to my Patent No. 944,975, I prefer to arrange that this deflector shall give a good rapid stream of air along the walls of the combustion chamber. This distributing device may be can ried by any part of the combustion chamber as may be convenient.

It will be noticed that should air for any reason enter-the fuel reservoir, m, instead of water, then. this air will .bu'oble up thrc h the fuel, pass along to thc combustion aiamber by the pipe. 12, and thus ext-inguish the fuel flame. It is not essential however that the fuel reservoir, 77:, should be completely full as water from the tank, g,

would flow into the fuel reservoir at a very great rate as soon as air is admitted to tlr.

water tank, g. Thus the air in thetop of e fuel reservoir, m, would be rapidly com- 5 pressed and ejected through the jet, If desired the water may be introduced into a l separate evaporating chamber instead of directly into the combustion chamber, c. The flow of fuel into the combustion chamber, c, i may be controlled bv the resistance of the spray, w, or other tacle in the fuelconduit, 1):, or by throttling the pipe, lc, leading the water into the fuel reservoir.

In a modification as shown in Fig. 2, I draw the water supply from the sea or from a supply carried in the torpedo by means of 9. pumpfm, driven by the engine or independently. When 9a water is used an anticorrosive substance such as an alkaline carbonate or hydroxid should be introduced. preferably by feeding a solution of the same :rinto the combustion chamber, or other g suitable place, by any appropriate method 1 such as already described in connection with the feeding of water. I may however, as shown in Fig. 2, arrange that a part of th sea water shall be diverted thrmlgh a ves el or tank, 3. con aining an anti-umrosive liquid or soluble solid, a suitable arrangement 5 of cocks may be provided for regulating the flow through this vessel. If the water is fed from a tank it is preferable to introduce iany such anti-corrosive substance directly linto the tank itself. A safety cock. is also provided to control the pipcs. and 1;. together with it, if desired, and the connec- 5 tion between the pipes It and may take The passage for mow:

place thro h the cock as described in connection wi 3. The pump may be rovided with rehef valves or other suitable devices (not shown in the drawings) for 8 the pressure of the water. It be seen, that, when the water is thus fed bymeansofapump,alargeairs mthe topofthe fuel nservoirmayp uce a misfire'unless the pump, 2, has a verydarge 10 mpacity. As the water supply is limited -;any"such space would take a considerable -''time to of and meanwhile com- .o pressed would be flowing backward the water and fuel jets (i and w) v I5 and would have to be subsequently expelled before ignition could take place. In order to overcome thae dificulties I prefer to use a fuel reservoir as shown in Fig. 2. Here it will be seen that the pipe, k, which conveys the water into the fuel reservoir, m, o

beneath the hell, 1. Thus air passing a ong throughthejegiandpipglgwouldbe caught in the hell, 1, and would not be able to bubble through the fuel and-subsequently PIS back to the combustion chamber. Any air therefore contained in the top of the fuel flask would be rapidly expresed therefrom and the feed offuel quickly established. In order that the hell, 1, may be completely filled the fuel reservoir is preferably filled in an inverted position through the plug, 2. The above could also-be overcome by-the use of a bag the fuel reservoir and so to se rate the water from the fuel which could 2 led either to the inside or the outside of this bag. By this separation air a along the water supply pipe into the reservoir would be prevented from passingon toth'e fuel jet. .Thefuelwillbefedb thecdlapeeorexpansion ofthebagdepen u whetherfuel orwateriswithinit. fif an an cause the pump should draw of water, this air will occupy small volume after compression and fore expel but little fuel from the fuelflask. Ifthepumpbreaksdown the fuel aimmediately ceasa.

It seen that by the present invention the feed of fuel 3 absolutely dependent upon the flow of water into the combustion chamber or other evaporating chamber. Thus should any blockage such as might be causedby occurinthe ipe,k,con-

veying the water to the combustion chamber between the water tank, 9, and the point at whichthe connection, k, is made to the fuel reservoir, it will be seen that no fuel is fed. A similaresult follows a burst pipe in the water system. If in the arrangement shown in Fig. 1 the water tank, 9, is not filled or the supply from any cause becomes exhausted, air instead of water passes through to the combustion chamber, 0, and a t! into the fuel reservoir, m, where it-rises through the fuel and passes along the-pipe,

F n, to the combustion chamber as already erplaiued. Thus again the feed of fuel 15 stopped upon failure of the waterv supply.

casioned by the high temperature of the gases without the cooling by the introduction of water or other vaporizable li uid are thus avoided. Further as the latent of steam is 'very large and its specific heat greaterthan that of air, the amount of heat taken up by the air is very small compared with that absorbed by the water and once variations in the ratio of fuel to air are of much less im ortance than are variationsin the ratio of fiiel to water.

It will be win that according to the resent invention the rate of the flow of fuel of the water or other vaporizable liquid and 'hence the pro rtion of fuel'to water is maintained sub: thus obtain the maximum amount of energyfrom the given store of compresed air or other gas suppo the combustion by burning in it as muc fuel as posible and feeding into the products of combustion a definite amount 0 water to reduce the temperature to a utilizahle degree.

The ratio of'fuel to water depends, of course, upon the relative resistances of the two systems, reckoned from the point at which the'pipe ls, conveying water to the fuel nservoir, m, is connected to the main water conduit, Ia, as the difierence of pressame as that by which the water is forced through the terminal portion of the water sistem. The resistances of either or both of t 68 water can be obtained. It will be seen that many may be made in the method of carrying invent on into effect without. in any parting from the spirit of the same.
